      I did a bit of research and found the most suitable pinouts, but I need to know which voltage the output is. It is placed near the CPU. This is a Chinese Android Karaoke box. The problem is its dead with only charging light. I did replaced some other broken LDOs. This one seems to be shorted ground pin to output with 26ohm. I removed it to check and it is still shorted.
